How do Li batts work for charging efficiency anyway? Wets go crazy for heat loss going past 80% SOC on up. AGMs heat up too.
If Li batts have better charging efficiency, then a straight AH counter when charging would be more accurate than with Wets. (The Trimetric has a built -in allowance for heat loss while charging, but it is not expected to fit all batts. You can adjust that if you do enough trial and error work on that for your own set of batts)
Not sure what it means that Li has that slow rise in voltage. I doubt it means poor charging efficiency. ?
